The five numbers 4, 9, 15, 20, and 27 are placed in the boxes below to make a true statement. What is the sum of the numbers placed in the boxes in the numerators on the left-hand side:
\(\[\frac{\boxed{\phantom{99}}}{\boxed{\phantom{99}}} + \frac{\boxed{\phantom{99}}}{\boxed{\phantom{99}}} = \frac{9}{\boxed{\phantom{99}}}.\]\)
